Frequently asked questions

Find answers to common questions about our products and services

  • The exclusive filter-step internal design promotes faster liquid flow during filtration. Working alongside the external ribs that prevent airlock, this combination helps maintain a consistent, uninterrupted flow rate throughout the filtration process.

  • Yes, these funnels are steam autoclavable at 121°C (250°F), making them compatible with standard laboratory autoclave sterilization cycles.

  • The stem is parallel and measures 8mm O.D. (outer diameter). A parallel stem provides a uniform diameter along its length, which ensures a consistent and predictable fit when inserting the funnel into collection vessels or filtration receivers.

  • The external ribs create small channels between the funnel stem and the opening of the receiving vessel, allowing air to escape as liquid flows through. This prevents a vacuum from forming that would otherwise slow or stop the flow.
